Embodiment
Describe exemplary embodiment of the present invention below with reference to the accompanying drawings in detail.
Fig. 3 is the block diagram of communication terminal according to an embodiment of the invention.Fig. 4 is the schematic diagram of receiver according to an embodiment of the invention.Communication terminal comprises receiver 10, coupler 190, audio signal amplifier 200, controller 210 and receiver port 300.
Communication terminal generally includes keyboard 110, display unit 120, display driver 130, radio communication unit 140, phonetic entry/output unit 150, audio player 160, audio output unit 170 and memory cell 180.
Most of circuit of the baseband circuit of radio communication unit 140 and controller 210 are integrated into a commercial integrated circuit (IC) chip.This IC chip comprises hardware, digital signal processor and the basic purposes microprocessor of communication process special use by being called mobile base station modulator-demodulator (MSM) chipset.IC chip processed voice and data communication, and according to the signal controlling whole system of keyboard 110 input.
According to embodiments of the invention, communication terminal comprises coupler 190, is used for audio signal is divided into two different audio signals of phase place each other; Audio signal amplifier 200 is used for audio signal with coupler 190 output and is amplified to and has predetermined gain amplifier, and it is outputed to hearing aids coil 18; And controller 210, be used to control the gain amplifier of communication terminal and audio signal amplifier 200.
For example, as hybrid coupler, coupler 190 is divided into two audio signals with the audio signal of phonetic entry/output unit 150 or audio player 160 outputs, and these two audio signals have same-amplitude, but phase phasic difference 90 is spent each other.One of two audio signals of separating output to the voice coil loudspeaker voice coil 13 of receiver 10, and another outputs to audio signal amplifier 200.
Communication terminal comprises receiver 10, and it is connected to receiver port 300 and exports the audio signal of communication terminal output.Receiver 10 is audio signal output unit, is also referred to as earphone, and is mainly used in the compact acoustic equipment.
Earphone jack 19 is made of a plurality of electrodes, and is connected to receiver port 300, is used to receive the audio signal from phonetic entry/output unit 150 or audio player 160 outputs.In receiver 10, permanent magnet 11 produces magnetostatic field.Therefore, when from the communication terminal input audio signal, the electric current that flows through voice coil loudspeaker voice coil causes dynamic magnetic field to generate, thereby produces Lorentz force.At this moment, owing to audio signal exchanges, so polarity (about 1/1000 second) in the very short time changes.Because the variation of polarity, the direction of Lorentz force also changes.
The size of Lorentz force is proportional to the length of flux density magnitude, current value, voice coil loudspeaker voice coil 13.The direction of Lorentz force is perpendicular to the direction on magnetic flux density and electric current formed plane.Therefore, vibrating reed 14 is owing to Lorentz force moves up and down, thus generation sound.
Second audio signal flows through hearing aids coil 18 through second output port 320 of coupler 190, audio signal amplifier 200 and receiver port 300, thereby produces induced electromotive force.Electromotive force has identical frequency with first audio signal that is input to receiver 10, but varies in size.From the audible signal of receiver 10 output with function of hearing aid is to increase audible signal by the induced electromotive force that voice coil loudspeaker voice coil 13 increases audible signals and hearing aids coil 18 to obtain.Therefore, the receiver 10 of dysaudia people by having function of hearing aid is than hearing sound better by traditional receiver.
The user sets volume by the UI that controller 210 provides, for example, and by pressing the button of lower keyboard 110.The volume that controller 210 is regulated according to the user calculates the gain amplifier of second audio signal, and the gain amplifier that calculates is sent to audio signal amplifier 200.
According to one embodiment of the invention, controller 210 utilizes the operation of serial bus control audio signal amplifier 200.In one embodiment, universal serial bus is I
2The C bus.I
2The C bus is also referred to as Inter-IC, is the bi-directional two-wire serial bus that provides communication to connect between integrated circuit.Phillips introduced I before 20 years
2The C bus is used to produce in batches product, for example TV, VCR and audio frequency apparatus.
Fig. 5 be according to an embodiment of the invention, the flow chart of the method for output communication terminal audio signal.
As shown in Figure 5, radio communication unit 140 extracts voice signal from the wireless signal that receives by antenna, and it is outputed to coupler 190 (operation S101 and S102).When the user imported the sound source play signal, the audio signal output that audio player 160 will be play from the sound source that is stored in communication terminal was to coupler 190 (operation S103 and S104).
An example of coupler 190 is hybrid couplers of exporting the signal of identical but phase phasic difference 90 degree of amplitude each other.At operation S105, coupler 190 will be coupled into identical but first and second audio signals that phase place is different of amplitude each other from the audio signal of phonetic entry/output unit 150 or audio player 160 inputs, wherein first audio signal outputs to voice coil loudspeaker voice coil 13, the second audio signal outputs of receiver 10 to audio signal amplifier 200 by first output port 310 of receiver port 300.
If the user imports volume, then calculate the gain amplifier of second audio signal corresponding, and send it to audio signal amplifier 200 (operation S108) with volume.Correspondingly, controller 210 supports UI by display unit 120.
The user sets volume by the UI that controller 210 provides, for example, and by pressing the button of lower keyboard 110.The volume that controller 210 is imported according to the user calculates the gain amplifier of second audio signal, and the gain amplifier that calculates is sent to audio signal amplifier 200.
The gain amplifier of slave controller 210 outputs sends to audio signal amplifier 200 by universal serial bus.In one embodiment, universal serial bus is I
2The C bus.Controller 210 calculates the gain amplifier of the volume corresponding audio signal amplifier of importing with the user 200, and this gain amplifier is passed through I
2The C bus sends to audio signal amplifier 200.
The gain amplifier of slave controller 210 outputs depends on the device that constitutes audio signal amplifier 200.Audio signal amplifier 200 amplifies from second audio signal of coupler 190 outputs according to the gain amplifier of controller 210 outputs, and amplifying signal is outputed to receiver 10 hearing aids coils 18 by second output port 320.The operation of receiver 10 is illustrated with reference to Fig. 1 and 2, omits its detailed description here.When audio call or sound source broadcast end, controller 210 shut-down operations (operation S109).
From top explanation as can be seen, according to being the method for dysaudia people output audio signal and the communication terminal that uses the method, because separating with the audio signal of leading to the hearing aids coil, the audio signal of leading to voice coil loudspeaker voice coil provides, therefore the output that can improve the hearing aids coil, and keep the signal magnitude of audio signal, and do not need to increase the size of receiver.
In addition, can regulate the gain amplifier of the audio signal amplifier that the audio signal that will output to the hearing aids coil amplifies according to the volume of user input.
In addition, the controller owing to communication terminal can pass through control signal such as I
2The universal serial bus of C outputs to audio signal amplifier, therefore is convenient to hardware designs.
Though described the present invention with reference to exemplary embodiments, persons skilled in the art it should be understood that the different variations that can make form and details under the situation of the scope of the invention that does not depart from the claim qualification.
